If an extinguisher has been partially discharged, it should be recharged or replaced at once. Some extinguishers- notably the dry powder type, will begin to leak the propellant gas, and lose all pressure within a few days. This is due to powder preventing the release valve from fully seating.
The amount of time the contents of an extinguisher will continue being expelled from an extinguisher when the extinguisher is "opened" to extinguish a fire depends on the size of an extinguisher and how the user chooses to employ it (continuous or in bursts). Most easily portable extinguishers will last for less than a minute if held open for continuous use.
